The O2 sensors and the shaking or engine miss will have little to do with one another
You need to do some misfire diagnosis
Compression test, injector flow test and coil test
You have codes for a misfire?
The 420 and 430 catalyst codes will have no effect on a misfire either
It's the other way around, sometimes a misfire can cause a 420 or 430 because the cat cannot keep up with the excessive HC's coming through

There are no misfire codes. 420 is stored but only comes active when the truck is ran a lot (over 100mi) and goes back off with in 3days.

So, on a 2006 E series van you think has a miss but the processor does not see it
That generally means a fuel issue
Like an injector that is not hitting or flowing
Last 04, 4.2 truck I had, I needed to replace 3 of them so I bought 6 Motorcrafts from China
Probably were knockoffs that had all the correct Motorcraft markings
A year later one of them failed and I had to replace it again
You might want to have the dealer clean your injectors from the rail (put nothing in the tank) (ever) but gas
A professional uses Injector equipment like mine one of which is this OTC

At $300 probably better to just replace all injectors.
Long before these injector cleaners came out, we all made our own out of old freon tanks or air sampler gas tanks for the I/M machine
All you need is pressurized air on top of some fuel to maintain 25 psi on the rail to clean them for hours if you want
I used to clean the injectors on my 83 BMW 633CSI for an hour every year, for 200k trouble free miles ,when everybody else was taking to walnut blasting for their intake valve deposits
The Ford injector sauce basically cleaned the whole upper end during the injector cleaning process (that combined with spraying half a can of carb foam down the throttle body to clean the throttle plate)
so i got 8 injectors and plugs coming cost $225 through rockauto. the miss is getting worse. what you are saying is making a lot of sense with the way it's reacted over the last few years. so a few hundred for 300k injectors and 60k spark plugs not a bad price. if i'm going to tear down and do testing i want the parts there to fix it. wife is in hospital so i've been going there daily but this need s to be fixed soon. changing fuel filter 60k and maybe pump also 60k.
Good luck with the wife
Wonderful
I'd do one thing at a time, but in your case, go ahead and do both repairs at once
If the fuel pump is factory, and only has 60k on it, I would leave it alone for now
